Hi,
First post here, so I don't know if it's the correct channel for this kind
of issue.
Sorry if it's not.
Since v 3.0 we can set path attribute as a callable in a
models.fields.FilePathField(),
as discussed here:
[https://code.djangoproject.com/ticket/29529]
and documented here:
[https://docs.djangoproject.com/en/3.0/ref/models/fields/#django.db.models.FilePathField.path]
The commit adding this feature can be found here:
[https://github.com/django/django/commit/ef082ebb84f00e38af4e8880d04e8365c2766d34]
I have an issue when I try to use django.forms.fields.FilePathField()
[https://github.com/django/django/blob/stable/3.2.x/django/forms/fields.py#L1095]
In the case where path is defined as a callable, and
"os.scandir(self.path)" is called (as showed in
[https://github.com/django/django/blob/stable/3.2.x/django/forms/fields.py#L1126]).
I have this explicit error:
"scandir: path should be string, bytes, os.PathLike, integer or None, not
function"
If I monkey-patch "self.path" in the {{{__init__}}} method with a pre-
check similar to what it was done for the added feature
[https://github.com/django/django/blob/stable/3.2.x/django/db/models/fields/__init__.py#L1711]
it seems to solve this issue.
{{{
...
path = self.path() if callable(self.path) else self.path
for f in os.scandir(path):
...
}}}
I don't know if it's a bug or if I miss something using
models.fields.FilePathField() and django.forms.fields.FilePathField()
